One of my machines has not been able to connect since 11 Feb. It continues to try but receives a failed rsponse from ox.ac.uk followed by a line that says "No schedulers responded". As I quickly approach experiment completion, I'd like to get this worked out. While I've seen the thread that says there is trouble sending in more than 40 trickles, I don't follow what I can do about it, or even if this is the problem I face.

Suggestions anyone?

Hi Bill,
can you tell us more about that particular machine? What's so special/different about it than others machines you've got listed on your account. Which one is it?
Same internet connection?
Same antivirus and it's version?
A proxy/firewall involved?

Looks like it may be a laptop due to pentium M processor. Can you establish an internet connection then with this already open try the update command a few times. Does it still always fail?

Yes, it is my laptop "Pan". My laptop "Pheobe" also hasn't connected in the past few days but it is of less concern right now.

Pan has a continuous connection when I'm at my home office as I am now. When I hit update now, which I've done many times, it tries but fails with the same result each time... No schedulers responded. It has always worked fine but now no longer seems to connect. I've tried with and without Norton AV, same result.

The full address it should be trying is

http://climateapps2.oucs.ox.ac.uk/cpdnboinc_cgi/cgi

This works fine on my laptop and i'm not always connected. If its sending to another address post the full addy and someone else that uses that addy should tell u if it's working. Are you running the latest version 4.19 ?

The trickles are located at
C:\Program Files\BOINC\projects\climateprediction.net
and are about 1K in size...if you have more then 40 of them located in that directory, move the trickle files to another location (so that you will have less then 40 trickles in C:\Program Files\BOINC\projects\climateprediction.net) then do a manual update...then move the rest of the trickle files back to the same directory, followed by another manual update...this did the trick for me after 2 week vacation...don't forget to do a backup first...

Good luck:)

Ina menawhile, there is a simple method to overcome this problem...not to solve, i admit.
Close BOINC on Pan, ZIP the whole BOINC folder (as a backup), transfer it to a machine where scheduler works, run it so it can empty trickles, ZIP it again and put to whole thing back on Pan (while renaming original location just to security).

Success... I think.

I did what 'bosh suggested and it seemed to work. Pan now shows as being updated. None too soon either as the current experiment is 99.87% complete. Whew... 46 minutes to spare. We'll see if it starts updating automatically in less than an hour. It looks like my stats will get a good pop today.

Now, here's something interesting...
I had trickles dating back to 23 Jan. that had not been sent. The 40th trickle in that group was ready on 11 Feb., the same date as CPDN showed the last communication from Pan. So, if it was communicating why no upload of trickles? After this date no communication succeeded.

This looks like a trap people can fall into easily. It should be of concern as the general instructions say...

"Do I need to be on-line all the time while the software runs?

Absolutely not. Once you have installed the software and registered with the project, you are free to disconnect from the internet.

Approximately daily your computer will automatically try to "trickle" a small amount of data which is used by the project scientists to track the progress of your experiment if you happen to be connected to the internet. It is not essential to trickle data. However, an internet connection is required for the final upload of approximately 6 Megabytes of data..."

This should be changed, or the program needs to be modified to accomodate higher numbers of trickles. Somehow I don't believe that Pan would have connected successfully at the end of the experiment, but maybe it would have. We'll never know for sure now.

Thanks all for the assistance.

Bill

I'm happy that you succeded...with trickles. If trickles went fine, probably final upload would be ok as well.

Thanks for notiting the outdatet general instruction. It was not possible to spot this before it acctually happen or had been tested.
It's up to CPDN team to update those things. I also believe there are importants things to do such as new models etc.
It may be recognized as yet another reason for having phpBB forum again, where stickes/annoucements can be easily updated by moderators so that cpdn team can focus on more important issues.

Actually, my PCs using v4.19 uploaded fine, but could not send the trickles...and then I could not connect to the server...go and figure:)

Mind you, I be curious if v4.13 behaved the same...anyone?

Hmmm...are you on dial-up? I upgraded 6 machines (12 models total) from 4.13 to 4.19, &amp; everything went super smoothly, w/o any probs at all (except for that temporarilly downed Oxford upload server). Oh yeah...OS is WinXPro-Sp2.

Well, Further happenings...

First, Dial up??? Never. That's sooo passe.

The first attempt post new experiment start failed with a "No schedulers responded", but the resend a minute later succeeded.

On the second trickle 8 hours later, it succeeded too but then immediately returned a message I've not seen before...

"Got ack for result (null), can't find"

When I first had trouble with Pan, I updated it from 4.13 to 4.19.

That's a bit strange and the experiment continues to crunch. Is this message not significant?
